Focusing and mechanical design
Its ball-bearing rack-and-pinion focuser provides dual-speed adjustment, 2-inch and 1.25-inch sockets and an M54 × 0.75 female thread.
Imaging configuration
The sliding dew shield gives a 230 mm transport length and the tube weighs 1.5 kg. An optional TSFLAT60 preserves 360 mm f/6 and provides a manufacturer-stated 41 mm corrected field.
Manufacturer specification note
Technical table gives 143 mm backfocus from 2-inch socket and 158 mm from M54; prose elsewhere says 135 mm. Table values are retained and the discrepancy remains explicit.
